Adjacent to the Pilot Station, this ephemeral wetland is located in a low dune swale behind the Wash House Beach foredune. The wetland was formed due to changing patterns of sand deposition following the construction of a spur wall in 1971-2. The structure of the Wash House wetland is still evolving and the site is a unique natural and educational resource.
In 2001 and 2002 Camden Haven Community College and the Bushcare group commissioned two studies of the wetland – Flora and Fauna Study (Geoffrey James and Joanne Green; December 2001) and Wash House Beach Wetland Report (TF Rolls Forest Regen November 20020) to assess the condition of the wetland and make recommendations for its future management.
The reports identified that the wetland is home to several species of bats including the Little Bent-wing (vulnerable) and the Eastern Free-tail Bat (threatened). Also recorded on the site were several species of bird including the Glossy Back Cockatoo (vulnerable) and Osprey (vulnerable).
A boardwalk with interpretive and educational signage was constructed using Coastcare funds to increase visitor safety and enjoyment, reduce the high traffic impact and create all weather access to Wash House Beach.
